The cell object has a method to set the column span. I didn't notice the one for row span. Is there any solution to achieve vertically merged cells ? Inserting empty cells is not the perfect solution : every cell has borders, and if my "parent" cell has more text than other cells from the table, than its borders will be pushed to match the text, even if this could be avoided if there wouldn't be boundaries between the merged cells. Thus, other cells will be resized and this is undesirable.
If there isn't any simple solution at this moment, please approximate the time when this option will be available. This option is very important for our product.
